摘要：This work develops a heuristic method for the design of batch water-using networks of multiple contaminants with regeneration unit based on the concepts of concentration potential. A water-using network involving regeneration unit can be formed by adding the regenerated stream(s) into the network involving reuse only. In the design procedure of the network operated in a single batch mode, time is take n as the primary factor a nd con centration potentials as the secondary one. For the networks operated in a repeated mode, the design procedure is similar to that for continuous processes, besides designing the storage tanks with the rules proposed. Continuous regeneration unit is selected in this work. With the proposed method, the network structure corresponding to the minimum freshwater consumption can be obtained. It is shown that the method proposed in this article is simple, effective and has clear engineering meaning.

摘要：在时尚的大循环中,创意设计的力量不可小觑。时尚之于时装,时装一直是时尚的风向标,时装引领着人们的生活哲学,传递生活艺术的质感。作为一名时尚教育研究与传播的服装设计专业教师,在设计创新的思考方面,需要不断地开拓,特别是如何破解几百年来以西方为引领的时尚格局,在当今中国跨越式发展趋势下,树立东方人自己的时尚哲学,塑造本民族的服饰文化自信。

摘要：分布式废水处理系统集成的本质特征之一是通过最大程度减少不必要的水流混合量而降低系统的总处理量。根据这一思想,提出了一种基于启发式规则的方法设计废水处理单元有最大入口浓度限制的单杂质废水处理系统。首先依据提出的规则确定处理单元的执行顺序,并在此基础上建立初始网络结构;然后通过计算确定最终网络结构。在设计过程中,上述规则的运用和最终网络结构的确定需要与杂质负荷平衡、夹点确定等废水处理网络设计的基本概念以及入口浓度限制条件相结合。对文献实例的研究表明,结果与数学规划法的求解结果相当,但设计过程更为简单且具有明确的工程意义。

摘要：与只考虑直接回用的氢网络相比,具有提纯单元的氢网络能显著减少新鲜氢气的消耗量,但其设计及求解提纯目标值过程均更为复杂。对于单杂质、提纯单元采用固定浓度模型的提纯回用氢网络,结合此类网络的特点,提出了一种简捷法确定网络目标值。首先假设提纯后氢物流量足够大,由此得出初始提纯夹点。当初始夹点估算正确时,由夹点之下的需求物流和源物流的流量与杂质质量衡算即可得出提纯回用氢网络的目标值;当初始夹点估算不正确时,可以第一次计算结果为基础判断得出正确夹点,再增加一步简单计算,也可得到提纯回用目标值。计算实例表明本文方法计算简单且有效。

摘要：《西游记》成书于庄学兴起之际,其创作思想、框架结构、写作手法和情节内涵等都有明显的庄子思想的影迹。如"相召""相累"的西游世界、寓言式的创作思维和"万物为一"的精神旨趣,都能看到庄子对《西游记》的沾溉。

摘要：高职高专院校的会计实训基地是会计专业学生进行实训实习活动的重要场所,加强实训基地的建设对培养学生的实践能力具有重要作用。目前会计实训基地建设普遍存在资金投入不足、实训项目和功能不全、实训室管理机制不健全等问题。高职高专院校会计实训基地的建设,要按会计实际工作流程来设计实训项目,真实再现会计工作的过程。要将会计实训基地建设成为高仿真的示范性实训基地,使之不仅成为学生的实习基地,还要成为综合开放基地、对外服务基地。

摘要：商业银行特别是大型商业银行信息系统是国家重要的关键信息基础设施,密码技术的应用对信息保护至关重要.传统信息系统各自建设密码服务功能,存在重复建设、专业性差、维护成本高、易出现安全隐患等问题.企业级密码服务平台是在商业银行信息安全架构实践基础上,运用SOA技术,将密码服务从各应用系统中解耦,实现密码服务功能的组件化、标准化、智能化和参数化,为企业所有信息系统提供组件式密码服务,提高应用系统开发效率,有力保障商业银行网络和信息系统安全.

摘要：为探讨直播水稻品比试验常规粳稻的适宜播种量,以常规中熟中粳扬粳3012为试验材料,设计4种不同的播种量和机条播、人工撒播2种播种方式,分析播种量和播种方式对出苗、秧苗素质、茎蘖动态和产量的影响。结果表明,随着播种量的增加,基本苗数增加,成苗率下降,秧苗素质下降,最高茎蘖苗和有效穗数上升,成穗率下降,理论产量和实际产量先上升再下降。扬粳3012直播品比试验播种量以60~90 kg·hm^-2为宜。
